LEER FOR CONTINUOUS SHEET' GLASS Filed July '14 N@ NEY.'

to spread1 or dil'use the heat from the burner, but also protects theburner' from falling glass, shields the glass sheet from a large portionof the carbon deposits that might result from the direct application ofthe heating Haines, and also assures an easy and uniform combustion atthe burners due to the feeding airl currents that will be set upcentrally beneath the cover shields. lVhile the shield shown is of sheetmetal, it could be built of clay or carborundum or other heat-rresisting material.

Obviously,- other forms of heating elements could be substituted, withlike results, for the gas burners 5.

Claims:

l. In combination with a leer and a Conveyor for carrying a continuousstrip of glass therethrough, a plurality of heating elements positionedat spaced locations in the leer, and heat radiating and dellectingelements positioned between the heating elements and the sheet.

2. In combination with a leer and a conveyor for carrying a contil'iuousstrip of glass therethrough, a plurality of heatingr elen'ientspositioned at spaced locations in the'leer, and a heat radiating anddeecting member positioned between cach heatingele nient and the sheet.

3. In combination with a leer and a eonveyor for carrying a continuousstrip ot glas therethrough, a heater in the leer comprising a burnerpipe provided with a series of gas openings which supply the flames, anda shield mounted between the flames and the glass sheet.

4. lIn combination with a lecr and a conveyor for carrying a continuousstrip' of glass therethrough, a heater in the leer comprising a burnerpipe provided with a series ol' gas openings which supply the ilaines,and a metallic shield mounted. between the flames and the glass sheet.

5. In combination with a leer and a conveyor for carrying a continuousstrip of glass therethrough, a heater in the leer ooinprising a burnerpipe provided with a series o gas openings which supply the llames, anda shield member mounted above and at the sides of the burner so as toradiate heat therefrom or deflect heated gases 4therearound, anddiii'use the burner heat across a large area of the sheet.

t5. In combination with a leer and a conveyor for carrying a continuousstrip of glass therethrough, a series of burners positioned at intervalsthrough the leer, and shielding means positioned between the burners andglass sheet.

7. In combination with a leer and a conveyor tor carrying a continuousstrip o glass-therethrough, a series of burners p0- sitioned atintervals through the leer, and a series of shielding means arrangedbetween the burners and glass sheet.

8. ln combination with a leer and a conveyor t'or carrying a continuousstrip of glass therethrough, a lseries of burners positioned atintervals through the leer, and a. shield positioned between each burnerand the glass sheet, so that heat must be radiated from the shields orbe deflected between the shields before reaching the sheet.

Signed at`(.`harleston, in the county of Kanawha, and State of lVestVirginia, this 1st day of July, 1924.
